The Thomas & Katherine Detre Library & Archives at the Senator John Heinz History Center is Western Pennsylvania’s preeminent source for researching the region’s rich history.
Access to the Detre Library & Archives at the Senator John Heinz History Center is free for all visitors. Visitors coming to the History Center solely to use the Library & Archives will not be charged admission; they will be given a special Library & Archives sticker at the Admissions Desk and directed to the 6th floor, where they will sign in. Paid admission to the museum is required to see the exhibits.
The Heinz History Center’s Detre Library & Archives is currently renovating its storage space. During this process, the Library & Archives’ newspaper holdings and a portion of its archival collections will temporarily be relocated to a secondary storage location. However, other archival collections are unaffected by the renovations.
